Goals outline
Goals - outline

  • Language change as an area to see `third factors’ at work.

  • Two Economy Principles

  • Linguistic Cycles

  • Feature Economy

  • Conclusions/speculations

Third factor flb e g chomsky 2007
Third factor (FLB), e.g. Chomsky 2007

(1) genetic endowment, which sets limits on the attainable languages, thereby making language acquisition possible;

(2) external data, converted to the experience that selects one or another language within a narrow range;

(3) principles not specific to [the Faculty of Language]. Some of the third factor principles have the flavor of the constraints that enter into all facets of growth and evolution, [...] Among these are principles of efficient computation"

If there are principles they should be visible in lg change
If there are Principles, they should be visible in Lg Change

Two main patterns (van Gelderen 2004 etc):

a) Phrase to Head

b) Up the tree: both phrases and heads

Principles: acquisition and derivation

A spec head
(a) Spec > Head

Full pronoun to agreement

Demonstrative that to complementizer

Demonstrative pronoun to article

Negative adverb phrase to negation marker

Adverb phrase to aspect marker

Adverb phrase to complementizer

And b higher in the tree
and (b) higher in the tree

On, from P to ASP

VP Adverbials > TP/CP Adverbials

Like, from P > C (like I said)

Negative objects to negative markers

Modals: v > ASP > T

Negative verbs to auxiliaries

To: P > ASP > M > C

PP > C (for something to happen)

Spec to head and merge over move

Late Merge

Head Preference Principle (HPP):

Be a head, rather than a phrase, i.e.

`analyze something as small as possible'

Late Merge Principle (LMP):

Merge as late as possible

Two problems w hpp and lmp
Two problems w/ HPP and LMP

Minor: Move is `just’ internal merge

Major: Language Change proceeds in a cycle. HPP and LMP are 2 stages but 2 more:

(a) how is the head lost,

(b) how is the specifier replaced

Head 0 is solvable e g iconicity
Head > 0 is solvable: e.g. iconicity

Null hypothesis of language acquisition

A string is a word with lexical content.

Faarlund (2008) explains that "the child misses some of the boundary cues, and interprets the input string as having a weaker boundary (fewer slashes, stronger coherence) at a certain point"

My alternative: Feature Economy

Some micro cycles
Some Micro-Cycles

Negative (neg):

neg indefinite/adverb > neg particle > (neg particle)


demonstrative > article > class marker


emphatic > pronoun > agreement


V/A/P > M > T > C


pronoun > complementizer

PP/Adv > Topic > C

Negative cycle in old english 450 1150 ce
Negative Cycle in Old English450-1150 CE

a. no/ne early Old English

b. ne (na wiht/not) after 900, esp S

c. (ne) not after 1350

d. not > -not/-n’t after 1400

Once, there are only uF on e.g. ne, a new element is needed. Hence, the cycle.

Cyclical changes are due to Economy

  • Negative, Demonstrative, Agreement, and Perfective Cycles, Clause marking Reason:

  • HPP and LMP, or

  • Semantic features are reanalyzed as grammatical (and interpretable as uninterpretable)

(2)& þær wearþ Heahmund biscep ofslægen, & fela godra monna; & [æfter þissum gefeohte] cuom micel sumorlida.

`after this fight, there came a large summer-force' (Chronicle A, anno 871)

`After this, Thomas came to Canterbury'.

Back to the smt
Back to the SMT

Language is a perfect solution to interface conditions.

Are both interfaces equally important??

Chomsky favors SEM/C-I: “the conflict between computational efficiency and ease of communication” is resolved “to satisfy the CI interface” (2006: 9).

I want to suggest:

The challenge the dual nature of n and v need for interpretable f
The challenge: the dual nature of N and V: need for +/- interpretable f

DP: Theta > discourse

(position > morphology)

V: Theta and TMA

Macro Cycle goes from (a) to (b) to (a) …

a) Movement links two positions and is thereby economical (=synthetic) = uninterpretable/EPP

b) Avoid syncretism; Iconicity is economical (=analytic) = semantic and interpretable features

Two forces
Two `forces’ interpretable f

  • Jespersen: "the correct inference can only be that the tendency towards ease may be at work in some cases, though not in all, because there are other forces which may at times neutralize it or prove stronger than it".

  • Von der Gabelentz (1891/1901: 251/256): "Deutlichkeit" ('clarity') and "Bequemlichkeit" ('comfort').

And uf is normal
And uF is `normal’ interpretable f

Chomsky (2002: 113) sees the semantic component as expressing thematic as well as discourse information. If thematic structure was already present in proto-language (Bickerton 1990), the evolutionary change of Merge made them linguistic. What was added through grammaticalization is the morphology, the second layer of semantic information.
